MEI 1 0f 3 FIG. 1.

BACKGROUND OF THE INVENTION Synthetic thermoplastic materials have found ever increasing usage in the recreational field for the various products offering play features to young children. Among the most successful items of continuing interest have been thermoformed plastic pools in various configurations such as those of Greenberg U.S. Design Pat. No. D-l95,l75, Greenberg et al., US. Design Pat. No. D-205,852 and Diemond et al. US. Design Pat. D- 206,750.

More recently, it has been proposed to combine other play features with a thermoforrned plastic pool. A particularly successful effort is represented by the pool with integral slide of Diemond et al. US. Pat. No. 3,497,877. In combining various play features with a pool structure, there arise many problems attendant to providing sufficient strength and rigidity and attendant to combining the features in a manner which is sufficiently inexpensive to permit appeal to a popular priced market; these factors represent a significant hurdle to be overcome in the design and manufacture of childrens pools with other play features.

It is an object of the present invention to provide a novel pool incorporating a seesaw subassembly permitting children to utilize the pool as a support for the seesaw.

It is also an object to provide such a pool in which the seesaw subassembly is readily removeable so as to permit full use of the structure soley as a pool.

Another object is to provide such a pool in which the seesaw assembly will not only pivot upwardly and downwardly but also rotate to provide a twirling action.

Still another object is to provide such a pool which may be readily and relatively economically manufactured and which is durable and attractive.

SUMMARY OF THE INVENTION It has now been found that the foregoing and related objects may be readily obtained in a seesaw self supporting pool assembly including a pool member formed from synthetic plastic material with a bottom wall, an upstanding post adjacent the center of the bottom wall and formed from the material thereof to provide a cavity therewithin, and a sidewall extending upwardly about the periphery of the bottom wall. A seesaw assembly includes a mounting member fitting about and removably seated upon the post, a pivot support mounted on the mounting member and an elongated seesaw member pivotably supported adjacent its center upon the pivot support for pivotable movement about the axis parallel to the bottom wall. The seesaw member has seat portions adjacent its outer ends for seating children by whom it may be pivoted to raise and lower the opposite ends thereof. The seesaw assembly may be readily removed from the post to permit unobstructed use of the pool member.

In its preferred aspect, the pool member is integrally formed from synthetic plastic sheet material with the post being formed from the material of the bottom wall. The post and support members are generally frustoconical in configuration and have cooperating and interfitting ribs and channels along the adjacent surfaces to prevent relative rotation and to impart relative rigidity thereto. The bottom wall of the pool member is greater in dimension in all directions about the post than the length of the seesaw member so that the children supported thereon will normally be within the confines of the sidewall of the pool member. To provide greatest play features, the pivot member is rotatably mounted in the support member so that the seesaw member will rotate about the post as well as pivot, thus providing a twirling action.

From the standpoint of pivot structure, the pivot sup port has a generally U-shaped portion through which the seesaw extends and pivot means seat in the legs of the U-shaped portion of the seesaw member to provide the pivotal interconnection therebetween. To provide the twirling action, a pivot member extends through the base of the U-shaped portion and through the top wall of the mounting member, thus providing rotatable support for the pivot member and the seesaw member. To prevent insertion of a finger between the elongated seesaw member and the pivot member, resiliently deformable synthetic plastic material is inserted into the spacing therebetween.

To provide a secure hand hold, handle means are fastened to the seesaw member intermediate the length thereof whereby children on the seat portions may have a readily available gripping surface. The handle means is conveniently an elongated member extending parallel to the seesaw member with reversely bent end portions of generally U-shaped configuration. In this embodiment, the free ends of the end portions are secured to the seesaw member while the elongated body portion is spaced upwardly therefrom. Most desirably, separately formed seats providing a comfortable seating contour and secured to the seat portion of the seesaw member are employed.

The term pool member as used herein includes structures which are inherently adapted to function as play pools for children although they may be used as sandboxes as well. Such structures have a generally planar bottom wall of substantial dimension so as to permit children to be seated and move about therein in various directions and are substantially free from any sharp contours which might impede use thereof for the intended purpose or endanger the children using same.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT Turning first to FIGS. 1-5, a pool with twirling seesaw embodying the present invention is illustrated therein with a pool or container member generally designated by the numeral 10 which is formed from an integral sheet of synthetic plastic material and a seesaw assembly supported thereon and generally designated by the numeral 12. The pool member 10 has a bottom wall 14 of generally planar configuration and an upstanding post portion 16 of generally frustoconical configuration adjacent the center there of formed from the material of the bottom wall 14 so as to define an open cavity extending inwardly from the bottom surface. Extending upwardly and outwardly from the periphery of the bottom wall 14 is a sidewall 18 terminating in a peripheral flange 20 of inverted generally U-shaped cross section.

The sidewall 18 is of generally circular cross section as defined by the generally circular bottom wall 14 in the illustrated embodiment, but it is comprised of a multiplicity of relatively shallow scallop or convexly arcuate portions 22 about its periphery and lying in a plane perpendicular to the bottom wall 14 so that the overall circular sidewall is in fact defined by a series of smaller radius arcs. The several scallop portions 22 individually slope upwardly and outwardly from the bottom wall 14 and converge in inwardly projecting ribs 24 which extend upwardly from adjacent the bottom wall 14 to adjacent the flange 20 to provide rigidity and enhance the strength of the sidewall 18. For a similar purpose, the sidewall 18 is also provided with a series of shallow arcuate ribs 26 extending between adjacent vertical ribs 24 generally parallel to the bottom wall 14 and opening generally upwardly.

Turning now in detail to the seesaw assembly, this is best illustrated in FIGS. 6-8 and includes a mounting member 30 of a generally frustoconical configuration which fits about and snugly seats upon the post 16 of the pool member 10. As best seen in FIGS. 4 and 6, the post and mounting members are provided with cooperating, generally axially extending ribs 32, 34 which are formed so as to extend alternately inwardly and outwardly. In this manner, outwardly projecting ribs 32 on the post will extend into and seat in channels formed on the inner surface of the mounting member 30 and defined by outwardly projecting ribs 34, and inwardly projecting ribs 34 on the mounting member 30 will extend into and seat in the channels fonned on the outer surface of the post 16 and defined by inwardly projecting ribs 32. This arrangement prevents relative rotation between the post 16 and mounting member 30 and greatly enhances the rigidity and strength of the assembly.

Mounted on the top wall 36 of the mounting member for rotation thereon is the pivot bracket member gener ally designated by the numeral 38 and generally of U- shaped configuration to provide a pair of upstanding legs 40 and a connecting web or base 42. As best seen in FIG. 7, the bracket member 38 is secured to the top wall 36 by a rivet or similar fastener 44, and washers 46 are provided on both surfaces of the top wall 36 to facilitate relative rotation, minimize abrasion and enhance the strength of the assembly.

Mounted for pivotal movement between the leg portions 4Q by the rivet or similar fastener it; is an elongated tubular or seesaw member 56 of generally circular cross section except at its ends where the upper portion is flattened as best seen in FIG. 8. To prevent possible injury to children, a block 52 of resiliently deformable synthetic plastic foam is inserted between the legs 40 to fill the space between the web 52 and the tubular member 50, thus preventing the insertion of a finger thereinto and possible injury. The block 52 is held in position by a rivet or similar fastener 54.

Mounted on the ends of the tubular or seesaw member 50 are synthetic plastic seat members generally designated by the numeral 56 and having a top wall 58 and a generally depending flange 68 about the periphery thereof. The flange 6% is configured so as to provide an upwardly extending portion which increases in height toward the outer end of the seat member 5a and becomes double-walled thereat to provide a cross section of generally inverted U-shape. The seat members 56 are molded to provide a pair of depending parallel walls 62 defining a channel therebetween in which is snugly received the flattened end portion of the tubular member 50, and a depending end wall 64 extends between the parallel walls 62 at the outer end thereof to provide an end abutment for the tubular member 5! The seat members 56 are secured onto the tubular member 50 by a pair of rivets or similar members 66.

A handle or grip member 68 of elongate configuration with reversely bent end portions 70 has its body portion spaced upwardly from and extending parallel to the tubular member 50. It is mounted adjacent the central portion of the tubular member 50 by means of rivets or similar members 72 extending through the flattened free ends 74 which are slightly arcuate in cross section to conform to the contour of the tubular member 5! Although the cross section of the pool member may assume a variety of configurations including circular, figure 8, trilobal or rectangular, the preferred structures are generally circular in configuration so as to provide substantially equal spacing outwardly of the elongated seesaw member as it rotates therewithin. However, the generally circular configuration (or any of the other selected configurations) preferably employs generally vertically extending ribs at suitable intervals thereabout in order to enhance the rigidity of the sidewall. In the illustrated embodiment, these vertically extending ribs are provided by relatively short scallops or arcs of lesser radius than the radius of the overall pool so that riblike portions are formed at the intersections thereof. Depending upon the thickness of the sheet material from which the pool member is formed, the ribs may continue into the bottom wall to provide maximum rigidity. However, the depth of the sidewall drawn from the sheet material and factors of economy will generally dictate the use of a radius at the point of intersection between the sidewall and the bottom wall in which case the ribs will blend into the radius and terminate adjacent to but at a slight distance therefrom.

The rigidity of the sidewall may be further enhanced by ribs or corrugations extending transversely between the vertically extending ribs. In the illustrated embodiment, it can be seen that the wavelike scallops in each of the larger arcuate segments define a corrugation or rib therebetween. However, various other structures may be employed to achieve a comparable result.

The flange extending about the periphery of the pool member is particularly important in providing strength to the sidewall portion. It acts in the fashion of a hoop or other encircling band and its preferred U-shaped construction imparts substantial rigidity to the upper portion of the pool member sidewall. It will be appreciated that the actual configuration of the flange may vary and that it, too, may include stiffening corrugations or ribs extending along its length.

To minimize the chance of a child slipping on the bottom wall when the structure is used as a swimming or wading pool, the bottom wall is desirably formed with a slip resistant surface. This can be done by treating the inner surface thereof to make it relatively rough or it can be formed with stiffening deformations such as corrugations or ribs therein, such as may be fon'ned by use of a mesh structure in the appropriate portion of the forming mold.

Although injection, rotational and blow molding from thermoplastic materials and compression molding from thermosetting materials may be used to form the pool member, it. is most desirably and conveniently formed by pressure and heat from synthetic plastic sheet material in a conventional thermoforming operation. This may include various kinds of mechanical assistance in addition to air or other fluid pressure to effect the displacement of the sheet material. Exemplary of the thermoplastic resins which may be employed are polyethylene, polypropylene, nylon, impact polystyrene, ABS (a graft blend of styrene/acrylonitrile copolymer upon a butadiene rubber substrate), and various olefin copolymers.

The configuration of the post and mounting members may vary to include rectangular, oval and other cross sections. However, the preferred cross section is circular to facilitate molding thereof and the preferred overall configuration is frustoconical as in the illustrated embodiment. It should be appreciated that the actual cross section may deviate from a true circle due to the presence of ribs as hereinafter described.

In order to impart the maximum strength and rigidity to the post and support members, these elements are desirably provided with generally vertically extending ribs or corrugations as in the illustrated embodiment. By alternating the direction of the ribs or corrugations on the two members, ribs on one will fit into channels on the other in an alternating pattern, thus increasing the relative rigidity and providing a high degree of resistance to relative rotation. The length of the ribs and corrugations along the post and mounting member may vary but is desirably substantially the entire height thereof.

Although the pivot support may assume a variety of configurations and may be fabricated from a plurality of parts, preferably it incorporates a basic U-shaped element or yoke providing a pair of upstanding legs through which the elongated seesaw member extends. The pivot pin for the seesaw member may be seated in suitable apertures formed in the upstanding legs as in the illustrated embodiment, and that pivot pin may be a rivet, or a disengageable fastener of the nut and bolt type, or any other suitable member. The mounting means for the pivot support upon the support member and will include a depending portion which may or may not be integral with the body of the pivot support. Most conveniently, it is provided by a separate fastener extending through the web of the U-shaped pivot support and washers or other suitable bearing surfaces are disposed on the opposite surfaces of the top wall of the mounting member.

In the illustrated embodiment, the elongated seesaw member has been shown mounted in a fixed position. If so desired, the elongated seesaw member may have several holes spaced along its length and the pivot member may be removeable so as to permit variation in the length of the seesaw member projecting on the opposite side in the conventional fashion to accommodate children of different weight. The elongated seesaw member is conveniently tubular in construction for greater strength and economy. It may be fabricated from synthetic plastics although generally metallic members are highly satisfactory for this purpose in providing the necessary strength commensurate with acceptable costs.

Although the children may hold on to the elongated seesaw member itself, it will be generally advantageous to provide a separate handle or gripping means disposed above the plane of the seesaw member. Although separate handles may be employed adjacent each of the seats, a single tubular member can be provided with a complex configuration so as to provide gripping means adjacent both seats. In the illustrated embodiment, a tubular metal member is bent so as to provide end portions which are secured to the elongated seesaw member. Obviously, the handle member may be of synthetic plastic or of metallic construction; generally metal tubing is preferred from the standpoints of cost, weight and strength.

in the use of the pool, it will be appreciated that the pool member will be filled with either sand or water under normal conditions and that the weight of the medium introduced thereinto will hold the pool member firmly against the ground. Thus there will not be any tendency for the pool member to rise as a result of the seesaw actionv However, the relatively large dimension of the bottom wall and the concentration of weight through the post into the ground will impart stability to the assembly even in the absence of sand or water in the pool member.

As will be readily appreciated, the seesaw subassembly may be removed from the post at any time to permit utilization of the pool member per se with totally unencumbered playing area. Whenever the children so desire, the seesaw subassembly may then be placed upon the post to permit twirling or seesaw action. The children will be able to splash into water within the pool member, spraying themselves and each other with water as a part of the play action so desired.

Thus it can be seen that the pool assembly of the present invention is novel and provides highly desirable play action including not only a pool or sandbox type of activity but also a seesaw. The pool assembly may also include a twirling action and the seesaw subassembly may be readily removed when so desired. The structure may be fabricated readily and relatively economically and permits vw'de variations in size and appearance.
